Leave the Chat Room:

When user closes the chat room, then client application request to server to remove his/her name from server’s online user list. In client side the below method invokes –

private void Form1_FormClosed(object sender, FormClosedEventArgs e)

{

if (remoteObj != null)

{

remoteObj.LeaveChatRoom(yourName);

txtChatHere.Text = "";

}

Application.Exit();

}

In server side the “LeaveChatRoom()”method invokes, the code of that method is –

public void LeaveChatRoom(string name)

{

alOnlineUser.Remove(name);

SendMsgToSvr(name + " has left the chat room.");

}

Now server has deleted your name from online user list.
